ES1A Mini Ethernet to RS-232 Converters provide simple and cost-
effective solutions for connecting RS-232 devices to Ethernet networks.
ES1A converters make it easy to connect serial printers, copiers, building
automation, retail, point-of-sale, warehousing and banking equipment
directly into Ethernet networks.
ES1A converters support virtual COM port, console management, TCP
and UDP socket, serial bridge, modem emulation and custom
connections. Network addresses can be obtained dynamically or manually.
Simple Network Management Protocol (SNMP) is supported. Configuration
is accomplished through a web-based user interface.

Communication Modes
ES1A Ethernet to RS-232 converters allow you to connect serial devices
over a LAN or WAN. Serial devices no longer are limited to a physical
connection to the PC COM port. They can be installed anywhere on the LAN
using TCP/IP or UDP/IP communications. This allows traditional Windows
PC software access to serial devices anywhere on the LAN/WAN network.
Direct IP
Direct IP Mode allows applications using TCP/IP or UDP/IP socket
programs to communicate with the asynchronous serial ports on the serial
server. In this mode the ES1A is configured as a TCP or UDP server. The
socket program running on the PC establishes a communication connection.
The data is sent directly to and from the serial port on the server.
TCP Server Mode allows network devices to initiate a TCP connection to
the serial device connected to the serial port on the ES1A. This is also
referred to as reverse telnet.
UDP Server Mode allows network devices to initiate a UDP connection to
the serial device attached to the serial port of the ES1A. When using UDP
protocol the ES1A can be configured to broadcast data to and receive data
from multiple IP addresses.
Virtual COM Port
Virtual COM Port mode (also called RealPort, or com port redirection)
allows you to map a COM port on your PC to the serial port on your ES1A.
Using the RealPort software (included with the ES1A) you create virtual
COM ports on your PC. When your application sends data to this port,
RealPort redirects the data across the network to serial device connected to
the ES1A serial port. The network is transparent to the user application and
the serial device connected to the ES1A.
Paired Mode
Paired Mode (also called Serial Tunneling or Serial Bridge mode) allows
serial devices connected to two ES1A converters to communicate across a
network. The two ES1A converters automatically connect to each other.
In Paired Mode the heartbeat feature ensures reliable communications by
restoring the connection if communications are temporarily lost at either end
due to loss of power or Ethernet connection.

Other Communications Modes
ES1A Converters also feature the following communications profiles:
Modem Emulation Mode allows you to configure the serial port to operate
as if it is a modem. For legacy applications where a serial device is set up to
communicate through a modem, the serial device can now be connected to
the ES1A and communication occurs over the network. The ES1A emulates
modem responses to and from the serial device.
In Console Management Mode the ES1A can be configured for connection
to the management port typically found on network devices such as routers,
switches and servers. This allows remote management of the network device.
Communication can be accomplished using telnet to a specific port in the
converter.
Custom Mode allows you to custom configure the ES1A serial port and is
used if your application does not fit into any other predefined modes.

Indicators, Switches and Connectors
Link Integrity LED (Yellow)
When the yellow LED located on the Ethernet jack is illuminated it indicates
that a connection (link integrity) has been established between the converter
and a node on the network.
Network Activity LED
When the green LED located on the Ethernet jack is flashing it indicates that
data is being sent across the network.
Figure 3. LED Indicators on the ES1A
Reset Switch
The Reset switch is a recessed switch located on the side of the ES1A. The
Reset switch provides two functions:
Press and release within 10 seconds Resets the ES1A
Press and hold for more than 10 seconds
while powering up Reloads factory default values
Ethernet Port Connector
The Ethernet Port connector is a standard RJ-45 receptacle that allows the
serial server to be connected to an Ethernet network. On the ES1A two
indicator LEDs are built into the RJ-45 connector.

Serial Port Connector
The Serial Port Connector is a DB-9 male connector (configured as a DTE)
supporting RS-232 serial communications including TD, RD, TRS, CTS, DTR,
DCD, DSR and GND signal lines. Use a standard serial cable if connecting to a
DCE; use a null modem (crossover) cable if connecting to a DTE.
Refer to Appendices D, and E for connection pin-outs.
Power Connector
Power is supplied to the ES1A by a 5VDC 1200ma power supply. The
power connector is a 5.5mm by 2.1mm barrel jack. The tip is positive.
Connecting the Hardware
Typically, the ES1A is connected to a network via a hub, switch or router
using standard CAT-5 cable. Configuration is accomplished over the
network, or via a direct connection (see below) using the Web Configuration
and Management Interface
Configuration Connections
Your ES1A converter typically is configured over the network connection
using standard browser software. It also could be connected directly to a PC
network adapter. To do so an Ethernet crossover cable is required.
